turbostat could be terminated by general protection fault on some latest
hardwares which (for example) support 9 levels of C-states and show 18
"tADDED" lines. That bloats the total output and finally causes buffer
overrun. So let's extend the buffer to avoid this.
This patch also removes duplicated "pc10:" line to reduce buffer usage.
